Rating scale
- A very good resistance
- B good resistance

- – no data
- K no general statement possible
A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
Frequently Asked Questions
Which materials resist Benzene at high concentrations?
The materials with an A rating (resistant) for Benzene at 20 °C are: PTFE, PVDF, SS 316, SS 304, Aluminium, FEP, ECTFE/ETFE, Acetal (POM). These can generally be used in direct contact.
Which materials should be avoided with Benzene?
Materials rated D (not resistant) for Benzene are: PVC Rigid, EPDM, NBR, Polycarbonate, Polystyrene, Polysulfone, PETG. These should not be used in contact with Benzene.
Does temperature affect chemical resistance to Benzene?
Yes. 7 of 20 tested materials show a worse rating at 50 °C than at 20 °C for Benzene. Materials affected include: HDPE, PP, PVDF, LDPE, ECTFE/ETFE, Acetal (POM).
Is PTFE safe for Benzene?
PTFE is rated A for Benzene at 20 °C. A rating of A means resistant, B means limited resistance, C means partly resistant, and D means not resistant.
About this data
The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.
A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
